|Abstract:||The aim of this study was to compare the environmental impacts of 8 different viable technical alternatives for the integration of photovoltaic power plants into the low voltage electricity grid with a photovoltaic electricity share of more than 24 % of the electricity supply mix. The environmental impacts analysed were greenhouse gas emissions, cumulative energy demand, ozone depletion, human toxicity, particulate matter and ecotoxicity. The technical alternatives included expansion of the electricity grid, restrictive allocation of electricity supply limits, as well as the use of lithium-ion battery systems for electricity storage and demand side management (DSM). We applied a prospective life cycle assessment in order to compare the life cycle environmental impacts of the different technical alternatives of integrating photovoltaic power plants with a total peak power of 6 MWp into a 44 km long, low voltage electricity grid supplying 1900 consumers in Switzerland. We also analysed two different load profiles for electricity demand with low and high variability typical for urban and rural electricity grids, respectively.|
